Abstract:

The content of photosynthetic pigments in 30-day-old shoots of Scots pine grown under the influence of acetone extracts from lichens Hypogymnia physodes, Evernia prunastri, Ramalina pollinaria, Xanthoria parietina and Cladonia arbuscula was studied. Extracts were on the surface of the substrate of seed germination and under it. With direct contact of sprouts of Pinus sylvestris with extracts from Hypogymnia physodes, Ramalina pollinaria, Xanthoria parietina and Cladonia arbuscula, an increase in the content of chlorophylls and carotenoids, a change in the ratios of chlorophyll a: chlorophyll b

The article discusses the results of biochemical studies of the content of chlorophylls a, b and carotenoids in the spruce needles growing in different conditions of the city of Ridder: control, parks, roads, zinc plant and CHP. Technogenic pollution of the Ridder air basin leads to the change in the content of chlorophylls a and b, carotenoids in the coniferous spruce. A significant decrease in the content of chlorophyll b and carotenoids in spruce needles was revealed in the following row of growing places: control -> parks -> roads -> zinc plant -> CHP.

Abstract. The study of the pigment complex of the main and lateral leaves of three dark-berry frost-resistant grape varieties of domestic breeding Vecherniy, Dmitriy and Kurchanskiy was carried out., The content of chlorophylls (a, b) and carotenoids in the phases of berry growth and ripening was determined using the spectrometric method. Based on the obtained data, the sum of chlorophylls, as well as the ratio of chlorophyll a to chlorophyll b and the sum of chlorophylls to carotenoids were calculated. It was revealed that the pigment content in the leaves depended on varietal characteristics

Introduction. The lipophilic fractions of many medicinal plants today are poorly understood, despite the fact that they contain such important biologically active substances as chlorophylls, carotenoids, tocopherols, phytosterols, fatty acids, phospholipids, etc., which according to the literature show reparative, anti-inflammatory, antiseptic, immunostimulant, antitumor activity. Compounds of lipophilic nature are carotenoids and chlorophylls are of great importance. Carotenoids increase the body's resistance to mutagens and carcinogens, reduce age-related degenerative changes in tissues, inh

C13-norisoprenoids have low threshold values in wine with the most prominent C13-norisoprenoids being β-damascanone and β-ionone which contribute honey and floral like aroma to wine. Chlorophyll and its derivates have also been detected in wine with potential to be precursors to aroma compounds.

Abstract:

When comparing ancient and modern rye cultivars, in addition to the difference in height, differences in the content of photosynthetic pigments in tissues are also noted. However, it remains unclear whether the change in pigment content is related to the change in plant architectonics. Plants of winter rye cultivars which differ in plant height were collected under the conditions of crop rotation of the Krasnoyarsk Research Institute of Agriculture. The concentrations of chlorophylls a and b and carotenoids were determined in the flag leaves and stems of winter rye at the “booting-earing” stag

Abstract:

The aims of this study were to investigate nutritional value of coldpressed sunflower oil produced in the Republic of Serbia. Composition of fatty acids was determinated and, based on individual fatty acid content, nutritional indices are calculated. Tocopherol composition and total content of carotenoids and chlorophylls were investigated as well. The results indicate that examined oil is rich in essential linoleic acid and with excellent values of nutritional indices. Unfavorable n-6/n-3 ratio is caused by low n-3 fatty acids content which is characteristic for sunflower oil. Total tocophero

Abstract:

This paper presents the influence of non-steroidal anti-inflammatory drugs (diclofenac, ibuprofen, and naproxen), antibiotics (ampicillin, ciprofloxacin), nanomaterials (CNT-COOH, CNT-MnO2 etc) and heavy metals (Cu, Cd etc) on the lettuce (Lactuca sativa L.). The evaluation of the impact of these pollutants on photosynthetic pigments, total polyphenols, antioxidant activity and the variation of multielement content was followed. From these studies it was observed that the VOCs emission rate increase with the increase of the pollutant concentration and the quantity of chlorophylls, carotenoids,

Abstract:

Fruit constitutes a major component of our diet, providing fiber, vitamins, minerals, and many other phytonutrients that promote good health. Fleshy fruits, such as tomatoes, already contain high levels of several of these ingredients. Nevertheless, efforts have been invested in increasing and diversifying the content of phytonutrients, such as carotenoids and flavonoids, in tomato fruits. Increasing levels of phytonutrients, such as lycopene, is highly justified from the perspective of the lycopene extraction industry due to cost effectiveness reasons. Diversifying phytonutrients, in particul

Abstract:

Global climate change and warming temperatures represent the greatest future challenge for global food production and quality. In this project, we will define the genetic factors of climate-associated taste deficiencies in carrot. Carrot is considered one of the leading horticultural crops in the world in terms of its nutritional value, health benefits, and unique flavor based on its high content of carotenoids and volatile aroma compounds. In recent years, carrot genotypes of different color with improved nutraceutical attributes have been developed. When exposed to high growth temperatures,

Abstract:

Hybrid vigor is the leading concept that rules crops breeding for almost a century. Yet, the exact mechanism that underlies heterosis is not clear. Over dominance interaction between alleles is one of the possible explanations. Our preliminary results indicated that severe developmental mutations at the heterozygous state have significant potential to improve plant performance. This led us to propose the ‘ODO breeding method’ that is based replacing a parental line of a successful hybrid with its mutated from to improve hybrid performance. Our BARD research challenged this method in three crop
